MEASURING MILK-CAN.

SPECIFICATION forming part of Letters Patent No. 397,788, dated February 12, 1889;

Application filed May 21, 1888. Serial No. 274,544. -(Il'o model.) I

To all whom it may concern.-

Be it known that I, RICHARD EAGAN, of the city of Syracuse, in the county of Onondaga, in the State of New York, have invented new l and useful Improvements in Milk-Cans, of l which the following, taken in connection with i the accompanying drawings, is a full, clear, E and exact description.

My invention relates to imprtwements in milk-cans of the class in which measuring-receptacles are secured underneath a portable fount or reservoir in which a supply of milk is kept, and the said measuring-receptacles are filled and discharged automatically through the medium of "alves attached to a spindle operated by a finger-piece secured to the handle; and my improvement consists in the detail construction and arrangement of the parts, all as hereinafter more particularly dea much better measuring milk-can is produced than has been heretofore made.

In specifying my invention reference is had to the accompanying drawings, forming a part of this specification, in which, like letters of reference indicating corresponding parts in all theviews, Figure 1 is a vertical section illustrating the general construction and arrangement of the parts. Fig. 2 is a top plan view of the top of the milk reservoir or fount detached, showing more particularly the opening and strainer in the top for the admission of the milk to the reservoir. Fig. 3 is a transverse section taken on the line 0/; 0c in Fig. 1, illustrating the interior construction of the 5 milk-can and the tubular spindles which carry 5 the operating-valves.

' The letter A represents the milk reservoir 1 or fount of the milk-can, which may be constructed of any desired size and shape. The milk-reservoir A is provided with the top B and the bottom B, as best shown in Fig. 1, the top 13 being provided with holes a through which pass the spindles which carry the valves J opening into the measuring-reeeptaclcs F, secured to the bottom B of the can A. The bottom 3 is provided with valve-seats f, Fig. 1, for valves f, mounted on a valve-stem, c, which will be presently explained. The measuring-receptacles F are secured to the bottom B of the milk-can A, and are of different 1 sizes-say one having the capacity of a quart, another the capacity of a pint, and so onaccording as desired, for measuring outmilk. The measuring-receptacles F are secured to the can A in a threaded socket, '1', as shown in Fig. 1, the upper partof the measuring-receptacle being provided with a thread, t, Fig. 1, which engages with the thread 0", depending from the bottom of the can A.

The obj eet of attaching the measuring-receptacles to the can A in the manner described is for the purpose of allowing the ready removal of the measuring-receptacles when. it is desired to cleanse the same, and the described means afford a most desirable securing attachment for this purpose, since either in easuring-receptacle can be securely attached and readily detached from the milk-can A.

In devices of this character as heretofore made and patented a difficulty has existed in the arrangement of the valves, which are usually attached to a rod at a distance apart sufficient to permit the closing of the opening which leads from the milk-can into the meastiring-receptacle when the exit-valve in the bottom of the 1neasuring-receptacle is opened to let out the milk therein, for the reason that, owing to the construction of the valves, a leakage would occur, and thereby the accuracy of the ineasuring-receptacle was practically destroyed. In order to overcome this defect, I mount the valves upon the stem extending directly through the measuring-receptacle, the lower end, (I, of said stem fitting in the exit-nozzle e and serving to guide the valvestem centrally in its vertical movement,

l thereby keeping the valve practically in line with its seat and preventing displacement when the valves are operated. I also secure the upper valve, f, to the stem in suitable proximity to its seat, f, which is formed in the bottom of the can A with considerable flare, so that when the valve g is opened the valve f immediately enters its seat, f, and thereby shuts off the flow of milk from the reservoir or can A into the 1neasuring-receptacle, and an accurate measurement is thereby secured. It will be observed that the form of the valve and its seat largely contributes to the efficiency of the arrangement, and the difiiculties due to the construction and arrangement of the valves in the prior devices are entirely overcome.

In order to permit the operator to readily control the delivery of milk from the measuring-receptacle, the valve-stem c is provided with the finger-ring a in suitable proximity to the handle H of the can tomake it convenient to grasp the ring (4 while the hand holds the can by the handle H and operates the valve by simply drawing upon the ring. A stem, 1), extending upwardly from the ring (1, passes through a hole, a, in the handle H of the can,and a spiral spring, 8, mounted 011 the stem 1, serves to force back the spindle 0, thereby closing the valve gin the measuring-receptacle F and opening the valve f, and the measuring-receptacle F is innuediately refilled with milk from the can A. Thus it willbe observed that the delivery of milk from the measuring-receptacle is readily accomplished by simply drawing up on the ring a in the manner described. If the receptacleA' were filled'with milk and no means were provided to allow airto enter-the measuringrreceptacle secured underneath the can A, the milk would" not escape from the measuring-receptacle, and the accuracy of measurement would'again be defective. Therefore, in order to secure the necessary air-supply Ianake the spindle or valve-stem c hollow, as shown in Figs. 1 and 3, and-perforate the space i above the valve f andbetween the valves f and g in the measuring-receptacle. 33- this constructionthe necessary supply of air is admitted into'the measuring-receptacle and its effective operation is thereby secured.

In order; to prevent the dripping of milk from the measuring-receptacles, and-at the same time to protect the nozzles e of such receptacles from dirt, &c;, andto afford a base which willmaintain the milk-can inan upright position, when notin use indelivering milk, 1 I provide-the cap 0, Fig. 1, thesaid'cap being provided with a rim, 0, havingtheoppositelyarranged slots-n n, Fig; 3, which allow the passage of pin-s mm, projecting from opposite sides of the ca-nA'near the bottom thereof, thesaid pins-and slots affording interlock-ingmeans whereby theeap (T is secured to the can A. A. flanged-rim, A, is secured to the can A, as shown in 1, and affords a support for the cap C, while the steps G G, projecting from-the base of the cap 0, afford a bearing for the foot of the operator-to enable himto remove the cap from: the milk-can, wh'iclris accomplished by resting the device on :the' door, placing the foot on the step G, and'turning the cairA byits' handle H "until thepins m. register'withwlre slots-n, when; the-can A maybe readily liftedfrom thecap and operated to measure and deliver milk automatically, as previously described. The

handle l-l is preferably constructed as shown in Fig. 1; but I' do not "restrict myself to'any' specific formof'construetion, since this 'feature may .be varied without departing from; the spirit of-my invention;

In the top 13 of my improved milk-can I provide an opening, D,- into which I secure astrainer, E, as best shown in Fig. 2, said opening D and strainer E serving to allow thecan A .to be filled with milk. It will be observed that when the valve-stem c is pulled upwardly by means of the ring a the valve f enters the valve-seat f, thereby closing the opening in the bottom of the milk-can A, while the valve g is withdrawn from its seat 9, and the exitnozzle 6 is thereby opened, allowing the milk to flow from the measuring-receptacle, and then the valve g closes automatically by reason of the action of the spring .5- when pressure is removed from the ring a.

The device is simple in construction, effective in operation, and affords a very desirable means for measuring and delivering milk,

producing considerable savin in the waste of milk incident to transferring it from the can to the measure and thence to a receptacle.

Having thus fully described my invention, What I'claim as new, and desire to secure by Letters Patent, is

l. The combination of the can A, provided with measuring-receptacles depending below the bottom of the can, a valve mechanism, substantially as described, operated from the top of the can to control the dew of the milk from the can into the receptacles and from the receptacles, and a detachable cap for inc-losing the measuring-rcceptaclcs, substantially as and for the purpose set forth.

2. The can A, having rim A and pins m, in combination with the cap (7, having rim 0, slots n n, and steps G, and the measuring-receptacles F, having valves for controlling the flow of milk from the can into the receptacles and from the receptacles from the top of the can, all substantially as and for the purpose set forth.

3. The combination of the can'A, handle H, rings (1, having stems 1), extending through holes av in the'handle H, spiral. springs .9,

-mountedon the stems b, valve-stems c,pro-

vided with .valvesf gin the measuring-receptacle F, the stem 0, having ends (I stepped in the discharge-nozzles e, substantially as and for the purpose set forth.

4. The combination of the can A, provided with the thread 1', depending from the bottom B, the receptacle F, having corresponding. thread, 7, valves f g, the combined airtube and valve-stein c, the operating-ring (I, located in convenient proximity to the handle H, and-the detachable inclosing-cap (1, all, constructed and arranged substantially as a nd for the purposeset forth.

In testimony whereof I have hereunto signed my name, in the presence of two at; testing witnesses, at Syracuse, in. the county of Onondaga, in the State of New York," this] 18th day of May, 1888.
